This invention relates to hydrodynamic power machine, and the object ofthe invention is the production of a hydraulic motor which is simple inconstruction and efficient in operation, and comprises comparatively fewparts.

Another object of the invention is the construction of a power machine,which utilizes water as the motive power and which machine or motor iscompactly constructed as well as being positive in operation.

This efiicient machine is an improvement upon the machine or motorCllJClOSBCl in my prior United States Patent No. 962,382, patented June21, 1910.

With the foregoing and other objects in view, my invention comprisescertain combinations, constructions and arrangement of parts as will beillustrated in the accompanying drawings, described in the followingspecification, and more particularly pointed out in the appended claims.

Adistrihutingr launder T is provided for allowing water to be fed to thefour compartments 2, 3. a and Two floats 8 and 9 are in compartments 2and 3 respectively, and are provi ed, near each end with a plate 10 to hthe lower ends of rods 11 are connected. Buckets 12 and 13 are mountedin com 'iartn ents 4L and 5 respectively. These buckets are each fittedwith plates 10 like the floats are. To the plates 10 of the buckets areattached the lower ends of rods 2 is a side elevation of the same. 3 isa front or inlet end of the d is a rear or discharge end elevashaft 16is connected to whatever machine is to be operated. The links 19 are.thereore, tta hed to Wha m g t e called the inner ends of shaft 16,whereas on the outer end of shaft 16 is fastened a rocker arm 20,through the outer end of which passes a stop rod 21, Figs. 2 and 7; thisrod 21 is prjvided with a pair of stops 22 that are th aded on the rod,for the purpose here- .1 e des ribed. Brackets 23 are mounted on thebody or casing 1, and suitably journalled 0n the upper end of thesebrackets are shafts 2 1 and 25. Vertical rods 11, which are connee-t edat their lower ends to the floats are pivotally connected at their upperends to the outer ends of rocker arms 26L The inner ends 27 of the:earms 26 are slotted, yoke shape to permit the extension to reach beyondshafts 2 1 and forconnecting the links 28, Figure 3. These links 28 formconnection from inner end of arm 26 to outer end of arm 18 and to upperends of rods 14-. Arm 18 is secured to the inner end of shaft 16. Rockerarm 20 is securely fastened at its inner end to the outer end of shaft10; through the outer end of arm 20 extends sait l rod 21 with saidadjustable nutelike stops 22, whereby the stops 22 can be adjusted onthe rod 21 for regulating the stroke of arms 29 and 30 fixedly securedto shaft 31. Rod 21 is pivotally connected at its lower end to one ofthe arms 29, Fig. '7.

Shaft 31 is journalled upon bearings 32 which bearings are mounted uponbrackets 33 of casing 1. Keyed to shaft 31 is an upstanding arm 34. i Arod is pivotally connected at its outer end to the upper end of said arm34, and its inner end is pivotally connected to arm 36. Arm 36 is keyedto latch shaft 37, which shaft 37 is suitably journalled on the sides ofthe casing 1. 38 is a valve shaft; the ends of this shaft aresuitahlyjo-urnalled on the side walls of the casing 1. Connected to shaft 38 arebutterfly valves or gates 39, 10, 41 and {12, located in frontof'compartments or chams oers 2, 3, 4: and 5 respectively.

Referring pa ticularly o gur 7 QII A rod 43 is fastened to toggle device44, and at its upper end extends through slot 45 in the upwardlyextending arm 29 fastened to shaft 31 This rod 43 is provided withadjustable stops 46 which perform in similar manner to stops 22. Thetoggle device 44 is pivotally connected at one end to a gate 15 and itsother end is pivotally connected at 47 to the slotted bracket 48. A rod43 is pivotally connected at its lower end to toggle device 49, thisdevice belng connected at its inner end to a gate 15 and at 50 tobracket 51. The upper end of rod 43 extends through the outer slottedend of the downwardly extending arm 29, on shaft 31 and on this rod 43are adjustable stops 52 for limiting the stroke of arm 29. I employ tworods 58 which are connected at their upper ends to arms 30 and are alsopivotally connected at their lower ends to toggle devices 54. The innerends of toggle devices 54 are pivotally connected at 55 to gates 56, andtheir outer ends are pivotally connected at 57 to the upper ends ofbrackets 58. It is to be noted that rods 43 and 43* work in the slots 59of brackets 48 and 51.

The action of this hydrodynamic power machine, in one complete cycle, isas follows: As shown in Figure 1, gates or butterfly valves 39 and 42are in a vertical position, or closed,and butterfly valves 40 and 41 arein a horizontal position, or open. Thus water entering through thedistributing launder 7 flows into (mmpartments 3 and 4. VVa-ter enteringcompartment 3 flows under the float- 9. ater entering compartment 4enters bucket 12. The weight of water entering bucket 12 will, throughits connecting links 14 and arms 26, tend to rotate shaft 16, while atthe same time, the water in compartment 3 will tend to raise the float9, which in turn, through its connecting links 11, arm 26, extension 27and links 28, will tend to rotate shaft 16 in the same direction as theweight of the water in bucket 12.

Shaft 16 thus being made to rotate will through the upward movement ofarm 20, at its slotted outer end, strike the upper stop raising theinner end of arm 29 and thus cause a clockwise rotation of shaft 81(Figs. 2 and 7). This rotation of shaft 31 will, through the outer endof arms 29 and 30, cause a downward movement of rods 48 and 53, thuscausing toggle devices 49 and 54 to straighten closing gates 15 and 56of one set; there are two sets of gates, one controlling the dischargeof a bucket chamber and the other controlling the discharge of a floatchamber; when the gates of one set are closed the gates in the other setopen so that the water may be discharged from the chambers of one setwhile the chambers of another set are being filled, that is, the watermoving into the chamber under one of the floats and into the bucket in achamber of the same set so that a float is being raised and a bucket isbeing filled at the same time in the same set, whereas in the other set,with the gates open, the water is being discharged out of achamber fromunder a float and out of a bucket in another chamber. The same rotationof shaft 31 will cause one set of gates to open while at the same timeclosing the gates of the other set.

Shaft- 38, through its revolution of 90 degrees will cause butterflyvalves 40 and 41 to be brought from a vertical to a horizontal openposition, as shown in Figure 1, and butterfly valves 39 and 42 from ahorizontal position to a vertical closed position as shown, thus closingpassage to compartments 2 and 5, and opening passage and allowing waterto flow into compartments or chambers 33 and 4. The gate 15 ofcompartment 5 and the gate 56 of compartment 2 having been open, throughaction of shaft 31 and its cooperating devices, and gate 56 and theother gate 15 having been closed, this condition of the gates will allowthe escape of the water from one set resulting in the movement of thebuckets and floats to rotate the shaft 16.

The stops 22, 46 and 52 are for the purpose of regulating the stroke ofthe arms in accordance with the rotation of shaft 31, it being desirableto regulate the opening of all discharge gates. The stops 46 and 52 arealso useful in securing an accurate movement of the toggle devices 44-and 49 to cause the tight closing of the gates to which they areattached.

From the foregoing it will be seen that my machine is very simple inoperation in that there are two sets of floats and buckets, each setcomprising a float and a bucket, means for alternatingly supplyingliquid simultaneously to a bucket in one set and to or under the bottomof the float in the same set, whereas in the other set, the water isbeing discharged from under the float and at the same time the bucket ofthis set is being emptied; these sets of floats and buckets areconnected by links or rods and arms to a rotatable shaft, from whichshaft power is derived for driving machinery.

Any suitable valve mechanism may be assembled at the intake end of themachine contiguous to the launder 7 to actuate rod 35 in time relationfor causing the uniform movement of the elements of one set of bucketsand floats in conjunction with the move ment of the bucket and float inthe other set: this valve mechanism comprising the shaft 38 and thebutterfly valve as herein before described to control the passage ofliquid or water through the launder into the compartments or chambers,as hereinbefore specifically described.
